Problem with after market driven pulley on trail master

[panchothedog]

High octane gas, low octane gas, booster, no booster. None of this is going to make a big enough difference one way or the other, unless you were measuring power output with very sensitive and sofisticated instruments. If the gas is clean, and relatively fresh, the engine will run just fine. Unless there's something wrong with it, like yours. You are putting way too much emphasis on whatever kind of hop up B S you poured in your tank. Everyday low octane cheap gas ( like what you put in your car to get to work and back ) is all that is required. Don't mix fresh gas with what's in the tank that was put in there by the previous owner, who knows how long ago. Empty the tank, go buy a gallon at the station, and you're ready to go. Pretty darn simple.

For kicks put the original muffler back on and see what happens. I’ll bet it picks up.

You literally said what I just said I was gonna do lol I already drained my tank and added gas. I just didn't drain the bowl nor did it run long enough to empty the bowl is what I was saying I know ima try running it befor I mess with anything. Bc I Definitely seen improvement. An to the muffler thing it was one of the first things I did to the cart. But I wouldn't waste no more time explaining other ideas until I test this really think it's just the gas fellas.. It ran great when I first put the fly wheel and air filter an now that I think about it I didn't add that booster bs till after running it for a bit. Then my issue started. I really hate to say it but I belive I have wasted the **** out of yalls time. Maybe not maybe so we will see

I don’t think it would have hurt anything. Does the booster/gas mixture light on fire when a lighter is put on it? And if it didn’t gunk up the carb, I don’t see a harm in it.

Waste of money for your engine, but I don’t think it’s the problem. As long as it’s just Regular Octane Booster and not RC Nitro fuel or something. Even then, a splash per tank probably wouldn’t hurt none.

I would imagine it is flammable but not positive. But looking at the gas when I drained my tank I poured enough to where it was discolored.. little orange looking so that's why I think I over killed it an the few things that pulled up when I Google it say over doing octane booster can Def cause ruff running etc

As much as I hope you getting running great, I feel so unsatisfied. You didn’t waste time. I only come here to waste time.

 

[Ryanhodge2715]

Lmao well look at it this way you educated a total stranger you'll never meet so there's that. Haha If it does work I'll lie an say I upsized the jet or something you suggested make you feel better Bob. I got you

Nah, don’t do that. I was expecting to find out that it was clutch misbehaving or something.

Or the coil...

 

[Ryanhodge2715]

Pos still doing it.... I drilled a tiny vent hole in gas caps too.... didn't fix nothing an now it leaks I'm just a damn genious

Leaks from where? If leaking from carb… it means issue with float, float needle, needle spring, or needle seat, right? This is the system that turns off the fuel supply so fuel can or cannot enter the bowl. When fuel level raises the float, the needle on the spring pushes against the needle jet seat and seals so gas stops flowing.

If splashing from tiny hole in gas cap, I’m not worried.

 

[bob58o]

Or the coil...

Based on how this has gone, I will suggest a valve job and new piston rings before I suggest the coil again.
Lol

 

[Ryanhodge2715]

Yea just from the hole I drilled.. what do you recommend valve lash Bob? I'm change them both to .003 test it then up size the jet befor I throw the towel in an just order few things...

 

[Ryanhodge2715]

Soo it wasn't this bad I changed seals last time I set the valve lash guess I over torqued it although I used a torque wrench set on 17 lbs an when I sprayed carb cleaner around it made no difference but now that I think of it. If this seal has been bad it wouldn't make rpms go up behind the valves huh. This may be my problem

 

[Ryanhodge2715]

Got this stuff.. ima set valve lash to .003 an run small bead of thus around the head. See what it does

 

[bob58o]

That seal just keeps oil in and dirt out.
0.003” should be fine. You are setting lash when both valves are closed right? At a specific point of rotation like piston at top dead center of compression stroke?

you are sure you aligned the dots correctly on the camshaft and and crankshaft gears? I noticed you said it fell out when taking the governor out.

I think one tooth misalignment would be advancing or retarding the camshaft 15 degrees, which is a large jump. I’m not sure it would even start. Perhaps it starts but runs poorly?

 

[bob58o]

Throttle linkage works properly to keep butterfly valve open when on it? I assume some changes were made after removing the governor?

 

[Ryanhodge2715]

Ok. Update! Bro I stg I went threw every jet I had originally an anything over 85 even with tuning all the way in an out would spudder. I originally just tighten the valve lash to .003 (1thing at a time) an I could totally tell rpm wound way higher but the spudder was still there. Went to the 90 an definitely better. But still there about to try the 95 an see. But I promise you when I did 90 or 95 before It shuddered right out the hole I'll let you know

Yeah man I bent me a nice close hanger rig works great

Right out of the hole might be the pilot jet. It controls idle and when start from a stop. I model that the main jet doesn’t kick in until 3/4 throttle. These carbs sometimes are hard to tune for smashing full throttle from stop. You can also try easing into full throttle slowly - as opposed to stomping on it.

The mixture screw basically only controls the idle circuit. It is fine tuning for the pilot jet.

 

[bob58o]

Different type of carb but…
First I tune the pilot jet, then the main jet after the pilot jet and air/fuel mixture screw

There is an overlap when both pilot and main jets are providing fuel. It’s easier to get it main jet dialed after the pilot jet.
