blaster not running after ridding short time?

[Murray777]

200 blaster; Running just fine, had lunch, will not start again!
Changed oil, cleaned: filter, new spark plug, gets spark, gas, took compresson test (60lbs) after several kicks, sprayed starter fluid in spark plug hole - put back in, kick but no start???

Any ideas?

low compression.... sounds like its time for a rebuild

your top end is done, it should be 120+.

Yup plus spraying starter fluid is a bad idea , no lubrication in it means you are basically dry starting the engine , it's bad

The low compression is a concern but believe it or not I had a Blaster that ran surprisingly well with 45 PSI. (don't ask me how) Even so, that is a pretty sudden failure. Unless you slagged the piston without noticing, compression just doesn't normally evaporate.

Run your comp test again just to be sure. It is important to hold open the throttle and kick until it stops rising, up to 20 kicks.

sure it can, will he's out riding and haveing fun the engine is hot, piston and rings are expanded out so they are squeezing a little more compression. Now go take a break, engine cools parts contract and you lose what compression you was running on.

Isn't that what I said?

That is very low compression. It's also possible your reeds just got frayed, chipped, or ate a lil making a motor already struggling to run, dead now.

Start with the basics before diving in head first to a rebuild.first things first do you have a manual?
