You're referring to the 'deflector' on the XL-923? It's just a 'spitback collector' (catches some of the fuel spit back out of the carb of reed valve saws......to be sucked back in) and isn't really needed. It just keeps the carb box a little cleaner/dryer.
I was referring to the C-52, but if it isn't needed, I won't worry about it.
I strongly suggest you rebuild the carbs and replace the fuel lines and filters on both saws. I have lines and filter on order for the 923. I'll have to get carb kits for both. Am I correct in thinking that I'll have to pull the fuel tank apart ont heC-52 to replace the lines?
As far as the 7/8 tooth question........what pitch chain are you going to run? I was thinking that I wanted to run a short, fat .404 on the C-52. It had been converted to 3/8, and had a red clutch cover and bar like the XL923. Both your C-52 and XL-923 will easily pull 3/8-8 on 20-24" bars. I would NOT recommend that you run .404-8 on either of them (stick with 7 tooth with .404). A 3/8-8 rim is about the same diameter as a .404-7 rim BTW.I fully intended to run 3/8 on the 923, but wondered about 7 vs 8. It sounds like 8 will work, so now to decide what length bar to get.
Strangely enough, I believe the three shoe clutch on the XL-700/800/900 series saws is the HD unit. My SXL-925 IPL states that the 3 shoe clutch was used on the SXL-925W (the "Western" version, with the full wrap handlebar......and intended for the PNW market where longer bars were usually used). My Western is so equipped. hmmmmm
The 77/82cc XL700/800/900 series saws used both 3 and 6 shoe clutches. They are completely different clutch setups (the 3 and the 6), with different clutch hubs, shoes, and drums.I knew the 3 shoe took a different drum than the 6 shoe, but had read a reference "somewhere" that the 6 shoe was the HD upgrade..
The C-series and Zip series used a different clutch setup than the XL700-900 series. Those large frame Homelites can also be found with 3 and 6 shoe clutches. However, with these large frame saws, they simply omitted every other clutch shoe to make a 3 shoe clutch (using the same clutch hub, shoes, and drum). This seems to only be on the C-5/51/52 and probably the Zip. It looks really weird (like something's missing), but that's the way they did it.
I believe the larger C-series saws (C-7/71/72 and C-9/91) had all six shoes installed from the factory. Same with the XP-Series saws (which are a continuation of the C-Series) The C-Series IPL's I've seen also state that C-5/51/52 saws outfitted with the gear drive conversion clutch cover should be equipped with all six shoes...
