- Have anyone filed piston oil-rings? - Team Chevelle
The oil rings are way bigger than the bore size I am building a 454 with 60 overbore (468) and now I am at the point of filing rings The rings are Mahle 4 310 + 005 file fit rings and the instructions states minimum gap for the oil ring to be 0015 The top and bottom rings are pretty
- AC Delco R45TS gap out of the box - Team Chevelle
Test engine was a 253 Cu in V6 Stock ign, 045 plug gap, it made 168 hp With Platinum plugs, same 045 gap, it made 171 hp Split Fire plugs, same 171 HP With surface gap plugs, 172 5 hp Then Jacobs installed one of his ign systems With same stock plugs, same 045 gap, hp increased to 180 5 With three specialty plugs, hp dropped 1 5-2hp
- Spark Plug Gap - BBC - Team Camaro Tech
Things that determine resistance is the plug wire conductor (metal conducts better than carbon impregnated fiberglass strands), the spark gap, and the resistance in the plug (the R in the designation of an AC-delco plug denotes an internal air gap to prevent power from bleeding off too soon)
- Poulan Ignition Module Gap - Arborist, Chainsaw Tree Work Forum
Gap is about the same as matchbook cover Wild things have a checkered past since most owners go wild trying to keep them running after a few years of use With spark trouble besides the coil check the flywheel, most of these had a built in key way cut into the flywheel that loosens up over time and throws the timing out
- Stihl Ignition Module Air Gap. . . - Arborist, Chainsaw Tree Work Forum
Next, the shop manual says to remove the setting gage, and measure the resulting air gap which is 0 008" - 0 012" Sounds easy enough Here's the problem, the stihl setting gage seems to set the air gap too tight, like 0 004" measured between the ignition module arms and the flywheel magnets using a feeler gage set
- Real world HEI spark plug gaps - Team Chevelle
If yu still see a specification for an incorrect giant spark plug gap for an HEi for any of the HEI's, DROP THE GAP DOWN TO THE PROPER SPECIFICATION OF 045 MAXIMUM All this was done in the divisions that designed the HEI, here in America, NOT some place in the middle of the Gobi Desert, nor Antarctica, nor the moon, but, here in The United
- McCulloch PM610 Which spark plug and how do I get it to run smoothly . . .
To wide a gap can be a problem It is common for electronic ignitions to go bad at or near a couple decades, and your symptoms are logical for either these parts failing Old fuel often causes problems in the fuel system but if it runs 10 minutes normal before faltering ignition components sound more likely to me
- Craftsman 42cc spark issues - Arborist, Chainsaw Tree Work Forum
A friend asked me to fix his Craftsman saw He said it wouldn't start It's a newer one (I believe a Poulan) Model 358 350880 When I check for spark using a tester with a light bulb in it it shows spark but with a different type of tester that actually sparks, no spark No spark when plug is
