But again very important to make sure your pan and cover is clean! I would suggest to check every time out when running open carbs!

If your going to keep the stacks on with spacer..
Come on your handy, make a mold off what you really need/want just use the bottom pan from whichever style is close to what you want so you just need to make the cowl..or just mod a cowl close to what you need...you don't have an old one you can use to start the mold off of?and mod it from there? And if you did that you should be able to find an old cowl that needs work cheap and start with that.. It's winter so winter project... on top of the checkmate..haha
Your going to be doing glass work on the checkmate..

Yes, cut from metal air boxes.
The little venturi tubes in the center are important.

Ya I could spend sum time making stuff ,but I need get the checkmate project done and motor for it will b on wild side instead mild side. Think I'm just gonna get a 260ish type cowl and b done. that way I can spend sum time getting this thing to fly. eventually

if ya lookin' for "ANY" performance gain ya lookin' in tha wrong place.. ain't gonna happen... I've done everything anyone can think of with carb motors.. 2.0's, 2,4's, 2.5's.. run 'em with/without everything anyone can think of.. stacks, stock airbox, modified airbox, no airbox.. cowl on, cowl off etc.. lotta work for absolutely no gain.. tha only thing I found that made any "noticeable" performance difference was completely different carb.. air delivery did nothin'.... jmo but i'm sure some are gonna disagree...….

**tlwjkw** · 10-22-2019, 05:00 AM

pretty much!

**tux974** · 10-22-2019, 05:18 AM

Tommy, WHO would argue with your knowledge?...

Heck,not even coffee stains interfere, you are still a sharp one!!!

"0" gain on stacks! I made them many years back because they looked cool.
I always thought if it looks good it will be faster.......

Just like when you wash and wax your car/truck it automatically runs better......

don't know how I remember have tha stuff 'bout these things??? 'bout only thing can remember!.. normal life nowdays.. I meet "new friends" every day and hafta ta ware a 24 hour watch ta know if its its day or night!... 7 day pill box with instructions on each compartment! (next ta tha coffee pot!)……. gotta be tough ta get old...

**Merc 2.5** · 10-22-2019, 05:46 AM

No like said in start of thread. not lookin or needing more power. just kinda like icing on the cake. And I do agree wit ya Tommy. Just more of a looks thing when sumbody ask me pull cowl haha

Since tux always great ideas to. I followed along with his he made. I made 1 from the plastic box to really just get a feel for it. I will remake one from metal box or get sum like Forbes has on his. So here's the rough mock up
