Bulb will be removed !
anti siphon valve already replaced..!
So an airleak would be a possible cause of the fuel issue then despite no sign of leaking gas
Pick up tube not yet replaced
Not sure if the trigger is the 2-Wire type but
Why would it fail only at low rpm’s ?
if purple wire drops...
plugs , Cap & rotor replaced end of season 24, plugwires + coil replaced last season
Carb rebuilt end of last season, but of course if there’s some debris in the fuel system the fine passages in the carb might be clogged on the very first run back home from the shop..
Totally agree re troubleshooting rather than fireing any cannon!
Ok so not the pump then most likely, Though it seemed as prime suspect as I ’ve had problems with engine not fireing up - solved by putting the primer bulb in the loop and manually pumping gas.
If there were some airleak due...
No idea of hours I’m third owner- (for sure the one adding the least hours to it)
looking back on my previous posts I realize I’ve done nothing but chasing various issues last few seasons
I did a compression test last year which to my knowledge showed the engine to be in ok condition 175...
forgot to mention,, when staring engine today I had blue smoke with the exhaust.. related to the suspected valveissue or yet another separate problem !?
So today I took belt off , however noise is still there. Did tighten the portside exhaust bolts a bit..( I’m getting concerned about the seemingly slopply job the shop did.). no change to the noise though
so now I need to look into the Valvetrain
1997 with mechanical fuelpump! (Not vortec)
Will test with belt off tomorrow -
Had exh system replaced last fall by Merc authoriest shop .. elbows risers manifolds ..
Have noticed this noise for some time but been busy trying to find the cause for engine dying when idleing/ low rpm..
AI tells me it could be related to mechanical fuelpump or valves.. Any input from a human would be highly appreciated..
After getting a sparktester I could actually verify spark to plugs.. this led me to take one step back and look at fuel as the culprit .. I disconnected my fuel hose (which contains a garmin fuel sensor and an inline fuel filter ) and replaced with a hose with primer bulb to allow me to manually...
