Governor Removal Problem

[jrmints1415]

This is my first time taking out the governor and im a little concerned. I bought a brand new engine from northern tool (powerhouse 208cc) and i feel like im destroying it. Have any of you felt like this taking out the governor for the first time?? I have some problems such as taking the gear off and im nervous because my cam and push rods fell out. I put them back in and i think it works but im just nervous. Any tips would be great!

Has engine been timed properly?
If so, there is little else to be worried about.
How many hours were on engine before it was disassembled?

 

[Doc Sprocket]

Make sure the timing marks on the cam and crank gears are aligned. Also, take the rocker cover off and make sure the rockers are seated properly on the valve stems and pushrods. They could have slipped out of place with the lifters out.

 

[jrmints1415]

It is a brand new engine without any run time which is why im nervous about it going right away without a governor

 

[Doc Sprocket]

It's a risk. Work slowly, pay attention, bag and tag parts as they come off, re-torque everything to spec.

Perhaps you should be nervous. I would have run it for a few hours (at least) with governor intact before any mods.
Who knows, you might have been happy with it in it's factory new state.

 

[Doc Sprocket]

Normally for the younger and less experienced crowd, I suggest using the engine bone stock until such time as the warranty expires. That way, any problems with the engine hopefully will have been identified, you're not "destroying a new engine", and you're not voiding your warranty. If you foul it up afterwards, you'd be on your own anyhow.

 

[jrmints1415]

ok now im really nervous! i already removed the arm and linkage but the gear is still on. Should i turn back now or is there no turning back?

 

[Doc Sprocket]

If you're that nervous, turn back now. Use up the warranty, then get crazy.

 

[jrmints1415]

but i already grinded off the top of the arm. still usable i think but will they take it back? and i cant get the timing right what do the marks look like? And also i am only nervous because i dont want to waste money not because i dont think i have the skill. Are the risks big or small?

 

[Russ2251]

Here is some help...crankshaft mark is not visible in this pic but is similarly marked to that of camshaft.

 

[Doc Sprocket]

Well, if you've cut the arm... In for a penny, in for a pound. work carefully and remember the cardinal rule. Once it's all back together and running, do not free-rev it. (revving up high without a load).

 

[jrmints1415]

do you think it should turn out ok? hey TS would you mind if tomorow you maybe could help me out ill post pics of it step by step and maybe you could help me through it so i dont mess anything up?

 

[Doc Sprocket]

I don't mind helping. In the meantime, have a good look around, there's lots of threads on this topic. Have you got a torque wrench?

I think tomorrow I'll be be making a new crankcase gasket for my own clone. That reminds me- have you got a new gasket?

 

[jrmints1415]

would i need a new gasket because i broke the seal? Thanks i appreciate it. do you think it will run again?

 

[Doc Sprocket]

There is a very good chance the gasket is not going to survive the surgery.

 

[KieranM]

Unless you ripped it, but its best to replace. Once you get it back together make sure the engine turns over freely (by hand) as in no parts are hitting each other which are not suppose to and just look at the various threads on here about governor removal.

Just a heads up: The OP's engine isnt the same as the GX200 or Jiang Dong/Lifan 6.5hp clones we're used to working with.

I've been researching and am fairly certain the Powerhorse 208cc. engines are manufactured by Liquid Combustion Technology, they claim "98% of its parts are not interchangeable with competing products" (clones)

These engines larger 208cc. displacement are not legal for most forms of clone-engine kart racing, so I wasn't able to find any info from kart racing sites or anywhere else on the net about Governor removal on one of these.

I did run across a report that GX200/6.5hp clone cams do not interchange, and that Parsons Racing Engines was manufacturing some racing parts to fit these 208cc engines. (but there's no info about this on they're site)

Anyways, my whole point here was just to warn you guys that the Governor removal procedure might not be the same for the Op's engine as a clone.

I'll be very interested in how this turns out.

 

[Doc Sprocket]

Thanks for the hot catch Ander- I assumed (oops) that they'd be the same. I would think that the procedure would be similar enough, though. Crack open the box, remove the unwanted bits, stitch it up, rig a new throttle.

Yep, hey I found an exploded view of his engine showing the governor assembly.
