Are you going to rebuild and try again?

Did a 2511t this weekend, hope to have it back together and test run tomorrow.

I compared it to my higher compression 2511t built by someone else, and it seems a little faster

Put a oem ported 64cc jug on for now debating oe79cc or am84cc i got a 2511t coming i got for 60$ might have to ask u about timing numbers u hit

might have to ask u about timing numbers u hit

I might have to ask me too, I just eyeball the 2511. I'd like to get a new electronic degree finder with chuck and holder that @Red97 is selling, so it's easier to time cylinders. I've tried both lowering the exhaust slightly, and raising slightly with good results. Never did much to the intake, just made it a tiny bit bigger. BGD, widen exhaust to 65% of bore or 23mm I think. I mark the width on a note card, then copy the marks to the cylinder after centering it how I like, more towards the exit side of the port. I round the corners slightly on the ends of the ring because they seem to quickly wear into the plating.

Do u know the numbers b4 and after?

 

[Nutball]

I only ever timed one, and not accurately, I just eyeball them. Not sure why I didn't time them. The only one I did time was a recipe I don't often use, but it had a lot of torque. 114, 130, 70 for what it's worth, but some of those numbers could be off by a 2-4 degrees according to my notes.

I'll let u know the oem numbers when I get the saw... I paid for it 3 weeks ago tomorrow... so it better come soon...wouldn't more tq be lower on the exhaust number near 100? Just finished this 205 with a 225 p and c i ported
