Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / February 2007305 chev engine starting problem
I have a jasper engine 50.000 miles in my 1967 nova ll. The engine started draging after shutting it down and starting it back up? I replace the batt. & 2 starters because the engine drags after warming up. I had it in the shop and they made a heat shield for the starter but nothing helps? Once it at normal operating temp. and I turn it off it drags so much you wouldn't think it would crank but it does? Elec windows drag too! Now I thinking it taiming problem but what would temp have to do with timing? I know it's something simple but it's got me! Thanks You could easily be describing a bad connection in one of the main power cables. The sneaky one is the battery to engine block connection and the engine to body one.

I don't know why temperature matters but I know it does. Try retarding the timing a little bit. Good luck >> I have a jasper engine 50.000 miles in my 1967 nova ll. >> [quoted text clipped - 23 lines] > temperature matters but I know it does. Try retarding the timing a > little bit. Good luck Hey, right on gxsr! He asked what temp had to do with timing--shoulda asked if both temp AND timing could make engine harder to start: yes! Advanced timing makes engine fire too early and "kick back" on piston's movement = hard to start, or "starter drag". Heat swells pistons--remember that piston "slap", a noise due to excessive piston-to-cylinder walls clearance? It is quieter when hot and is due to piston's expanding & reducing this clearance after it heats. This same swelling could cause "starter drag".

That's right, the easy way to check this is to disable the ignition system and see iff it still cranks hard. > Heat swells pistons--remember that piston "slap", a noise due to excessive > piston-to-cylinder walls clearance?

HTH, s An engine with too tight of a piston to cylinder clearance will have far worse problems than slow cranking when hot. |
