Blaster been sitting for 3 months and does not have no compression now

[Charlesh]

I had a problem with my blaster and got it fixed it was only the front sprocket did not have time mess with it over the last 3 months fix the sprocket try to start it and it would not start clean the carburetor test for spark. It had Spark so I did compression test and it is a zero jumps up to 20 then Falls right back to zero fast. Just did a top-end rebuild Maybe only 5 hours on it. Had it running 2 time in the last 3 months start it up easy and now doesn't want to start

Yep, defective gàge. Schrader valve is stuck. Even if it only had 20 psi gàge should stay at 20.

Try new plug and fresh fuel. Drain tank AND float bowl.

What is a schrader valve. I put fresh gas in it clean a carburetor in a brand new spark plug already

 

[Larry's Shee]

Schrader valve is the same as a tire valve stem, kind of a one way valve.

Ok

I know this is over a week old and problem may be solved but I want to add something. This may not be the case because I doubt it would leak that bad but when I compression tested my blaster when I first got it, it did the same thing only I could kick it fast enough to get it to peak at 60 psi and then dropped down. I found out that it was the head gasket leaking like crazy because it was installed upside-down by the PO. So it may not be the tester. May have a bad leak in the head gasket but I would try with another tester before checking the head gasket.

It was the topend it was 60 psi and the PSI gauge was messed up how to buy a new one
