More carb problems. 1982 Spectre 750

I thought it was a vacuum leak too and no it was not hooked to the petcock so i plugged the hole and the bike still ran the same way. I have an auxilary tank hooked up so i dont have to keep taking the tank off and putting it back on.

Did you spray around with carb cleaner? Did you do as Patton suggested and check both the valve clearance and compression?

i didnt do anything yesterday i plugged the vacuum line the other day. I wont be able to work on it for a few days unless i work in the night. aand the shed i have it in has no heat and its about 15 degrees here at night. but the next time i can work on it i will try what patton has said and i will check valves and compression and report back

So i finally had time to ad least check tthe compression and i got 160 on cylinder 1, 120 on cylinder 2, 140 on cylinder 3 and 130 on cylinder 4. im waiting to find my feeler gauge so i can do clearances. but there is the compression.

so im thinking my valves could use adjustment cause its always hard to start it an it backfires and runs like crap. So im going to go somewhere tonight to buy new feeler gauge and then ill check them later tonight.

Alright i got the feeler gauge and just got done measuring the clearances on the bike. When i list them. the order 1,2,3,4 will go as left to right when sitting on the bike.

Cylinder 1: Exhaust .006 Intake .004
Cylinder 2: Exhaust .004 Intake The .002 would not even fit. Thats the lowest i have.
Cylinder 3 Exhaust .006 Intake .002 would not fit
Cylinder 4 Exhaust .004 Intake .002 would not fit.
