Dmac68 Posted March 12, 2020 Author Report Share Posted March 12, 2020 Take your stator cover off. Take pic of timing plate. I pulled the stator cover off but you can’t really see the timing plate very well. Do I need to pull the flywheel ?

alcoholbanshee Posted March 12, 2020 Report Share Posted March 12, 2020 (edited) Snap a pic focusing on the right side of the flywheel, just above the pick up coil. Edited March 12, 2020 by alcoholbanshee Quote Link to comment Share on other sites More sharing options...

Envoyé de mon SM-G965W en utilisant Tapatalk Yup, I wanna know what the squish is and exactly what octane fuel you were using when it was backing plugs out. My guess is going to be poorly designed domes. I am assuming these are trinity domes, and that does not give me the warm fuzzies. Quote Link to comment Share on other sites More sharing options...

alcoholbanshee Posted March 12, 2020 Report Share Posted March 12, 2020 Do a search on how to do squish. It is super easy to do and all you will need is a couple pieces of solder and a good measuring device. I dont feel like typing a small novel on a phone......sorry lazy 1 Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted March 28, 2020 Report Share Posted March 28, 2020 I’ve gone through a few trinity motors with that same set up. At 160 psi with porting, the actual compression ratio will be a bit on the high side for sure. So you will definitely need to give it race fuel to keep the plugs from backing out. A 9 range plug may also help. Verify your stroke for sure stock is 54mm, 4mil Stroker is 58mm. Don’t be close, be sure Also, if you’re doing a 2/1 carb on a motor that size, make sure to have an upgraded larger single petcock, gutted check ball on gas cap, and a billit bowl on the carb. As far as squish test, you tube some of the South Texas Banshee stuff. He has video how to’s. You can also Google a guy that used to run a blog for banshees and blasters called MacDizzy. He used to put a lot of detail out on how to do all of that. Base gaskets play a role in all of this. Quote Link to comment Share on other sites More sharing options...

Do you have a part number you would recommend ? Also what fuel ratio / mix would you suggest trying ? I will look up the test and get that done soon !

If you’re buying from the Sunoco gas pump, make sure it’s a place with high turnover so the fuel is fresh. 9 range plug is just the heat range on plugs. Typically guys have an 8 heat range plug in them like B8es or BR8es. A 9 range plug is a cooler burning plug. Quote Link to comment Share on other sites More sharing options...
