Wont fire after rebuild


Recommended Posts

well go see what you get.

I got it to fire up. The only way that I could get it to run was to hold the throttle wide open while I kicked it over. It did run (like crap), but it ran. I had to keep the throttle open quite a bit in order for it to continue to run, After I shut it off I did a compression test on the right side this time (with the throttle wide open), the highest that I could get was 65psi.

 

My quess is that the shop that bored the cylinders over-bored them. Any other ideas of what could be causing this?

should be at the thickness of a business card.

I got it running. I installed an adjustable timing plate when I did the rebuild, I it set at +4 (lined up with the split in the cases). I put it back to zero and it fired up and I was able to drive it around a bit. I'm going to check the compression again tonight now that I have been able to run it for 15min or so.

 

Am I doing something wrong with the adjustable timing plate? I did double the intakes, carb boots and everything there looks good.

if you can only get 65psi after a rebuild, yes some one fucked up, either the shop over bored or you got the wrong pistons in it. ya got the rings in the right slots right? i would take it apart and see whats going on in your motor before it gets messed up even more
