10Hp Tecumseh Hating me

[solomon]

well i had it running the other day, it ran okay. I went to start it today and no start, so i checked and i had no spark, wasn't grounded so i checked the points and they were shot, replaced the points, gapped at .020 and now i have a nice spark, but now it only runs on a shot of starter fluid, clean gas, clean main jet in the carb, just took it apart and it looks fine, what gives?

 

[Kaptain Krunch]

Did you line the marks up on the cam and crank gear? was it running on THIS carb the other day?

Main jet means nothing, its your pilot jet that needs to be clean.

 

[solomon]

yup, running on this carb, and timing gears were aligned. Whats the pilot jet? the one that goes from the main jet into the venturi of the carb?

[solomon]

that is what i was referring to as the main jet, it is clean. I tried adding a different carb today (adjustable carb), but gas pours up inot the venturi. The float is set correctly and the bowl is on correctly.

 

[Kaptain Krunch]

If gas is pouring up into the venturi, the float obviously isn't doing its job.

 

[solomon]

yea the float was stuck, i fixed that, and now i can get it to start on choke and then remove the choke and manual rev it, but no idle. So im getting closer, what is now?

 

[Kaptain Krunch]

If it will only idle on choke, its lean.

This stuff is all pretty simple.

 

[solomon]

When i rev it i can feel gas spit out of the intake on me, so I was thinking rich, i tried turning in the bottom screw, assuming thats lean and it wouldn't start at all. Also i checked and i have no air leaks, motor hasn't run long enough to do a plug chop either, thanks

 

[solomon]

okay update, im getting no spark,again. Im getting oil all over my points. The seal looks good, and it never did this before. I put 1Quart of 5W-30 oil in it.

 

[freakboy]

synthetic?

 

[solomon]

motorcraft 10W-30 synthetic-blend

 

[Kaptain Krunch]

Use SAE 30, dont think thats your problem, but SAE 30 is best for warmer weather.

 

[solomon]

what could the problem be? This seems to be a very rare and unheard of problem.

 

[freakboy]

over a long time the build up of crap with normal oil helps seal better and synthetic removes all that crud and makes it leak like a sive... it happens alot with old engines that were never ran on synthetic the gunk helps seal and that stuff cleans it away and then it will seep past.

 

[solomon]

okay so i should try changing the oil with 30W Detergent oil?

 

[freakboy]

idk anything bout detergent and non detergent but as long as its pure dino oil it should be good enough.

 

[solomon]

haha okay so just some cheap low grade stuff, got it.

 

[Kaptain Krunch]

okay so i should try changing the oil with 30W Detergent oil?

SAE 30 will never hurt, but i doubt that will solve your problems (but it will prevent long term problems).

 

[solomon]

I just don't know what to do. The motor is useless right now, because oil get on the points and then they stop working and i have no spark. What do i do?
