Tomorrow I'm going to check timing g amd fuel pressure.
Sorry for askin all kinds of questions but I'm just trying to figure some stuff out
U might want to know this! But I put a 180 degree thermostat in it also and for the first couple of days the temp got up to about half way on the gauge. Now the past couple of days the temp gauge won't even get to the n. I know thst will make it run in cold loop mode and it's not good for the motor but it hasn't smelled like it's running rich.
Wouldn't running coldloop make it run stronger or am I thinkin wrong? And I felt the motor with my hand amd it feels like it's running at correct temp.
I thought my gauge was bad so I pulled the sender wire amd grounded it and the gauge pegs to hot. So I reckon I'm going to put stock thermostat in it amd c what it does. Thanks for all our help trogan horse !!
Yeah, don't use the colder thermostats. If anything get a high flow stat in the correct temp range.
Cold loop will make it over fuel and actually if it does that it will hurt your power and engine eventually. Running lean will increase power, but it can also be detrimental as you could burn a hole in a piston doing that. There is a fine line between rich and lean that you need to run in. Lean enough to make good power, but rich enough to keep from melting down the engine. Reading the plugs immediately after a WOT run will help you decide the correct fuel mixture or you could get a wide band gauge/meter to make that tuning easier.
If the engine is getting really hot that would explain why you feel like there is a loss of power.
