havent posted on here for a while but i have an engine problem

it is a .28 sh engine and it runs nicely through 1 tank and then it wont start on the second. the glow plug has been changed and the needles have been reset to factory standards.

can anyone think of what to do??

When you try to restart, hold the throttle open some. If it starts, your low speed mix is too rich. Check the plug for wetness. Also might want to check compression after the engine is hot. Since the liner expands at temp, it could be losing compression when warm. Worn out pistons create a nitemare to restart a warm engine. My SH .28 P6 restarts like a dream.

thank you i shall see what happens tomorrow and will update

i believe i have fixed it

by putting in a spare engine

Was the compression low on the SH?

The compression felt rather low from before, when I ran it,
However forgive me if I'm wrong but if it works for 1 tank then surely it should work for the next tank as the engine will heat up during running
